As others have pointed out in Alpha protection you have temporarily handed over control to the aircraft and until you exit Alpha Protection that's the way it stays. It matters not what you do with the T/Ls or sidestick as the nose down or nose up demand cannot be overridden in Normal Law! Once clear of Alpha and the ensuing TOGA Lock, you have full control back. If you suspect unwanted Alpha activation, that's when the AD must be followed and switch off 2 ADRs which takes no time and degrades you to Alternate Law and gives full control but no A/P or A/THR. Landing takes place in Direct Law once gear extended.
Benthere,
As someone who claims to have flown the Bus for 10 years, it sounds like you don't understand the fundamental laws which I find frightening!
